WORKHOLDER.

Application filed June 2, 1922. Serial No. 565,453.

To all whom it may concern:

Be it known that I, Finn) M. Bn'rrns, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Vorkholders, of which the following is a specification.

This invention is designed to provide a work holder for use in making small tanks 10 or boilers and is particularly useful in calking such tanks or boilers.

The invention is illustrated in the accompanying drawings as follows Fig; 1 shows a side elevation. 15 Fig. 2 a plan View.

Fig. 3 an end View of the cradle, partly in section.

1 marks the frame, 22 posts extending 9 upwardly from the sides of the frame, and

- 3 a cradle pivotally mounted within the frame on a pin 4 extending through the side walls of thecradle and through the posts 2. The cradle has the side walls and end walls, the end walls being provided with sockets 5 conforming to the walls of a drum or cylinder, said socket being open at the top and preferably slightly at one side. A drum 6 is shown in position in the slot and is secured therein by a clamping plate 7. Screws 8 extend through the side wall of the cradle for operating the clamping plate and a wheel 9 is provided for operating the screw.

The frame is provided with abutmcnts 10 at its ends against which the end of the tank abuts as the cradle is tilted in either direction.

In calking a tank the cradle is tilted in one direction and the upper ends of the tank, or boiler as then tilted is calked and half of the side seams. The cradle is then tilted in the opposite direction and the opposite end of the cylinder-or tank is calked and the remainder of the side seams. This reduces the time necessary to calk such devices vcry materially from practices which have been heretofore used.

What I claim as new is:-

1. In a work holder, the combination of a frame; a tilting cradle mounted in the frame, said cradle having a berth receiving the sides of the work and leaving the ends of the work exposed, and abutments engaging the ends of the work as the cradle is tilt d either d r t on.

2. In a work holder, the combination of a frame; a tilting cradle mounted in the frame, said cradle having a berth for receiv ing the sides of a cylinder leaving the ends of the cylinder exposed; and abutments engaging the ends of the work as the cradle is tilted in either direction.

3. In a work holder, the combination of a frame; a tilting cradle mounted in the frame and having a berth adapted to receive the sides of a cylinder; and means operating upon the sides of the work for securing the Work in the berth.

4.. In a work holder, the combination of a frame; a tilting cradle mounted in the frame and having a berth adapted to receive the sides of a cylinder; and means for sccuring the work in the berth comprising a clamping device operating from the side.

5. In a Work holder, the combination of a frame; a tilting cradle mounted in the frame and having a berth adapted to receive a cylinder; means for securing the work in the berth; and abutments adapted to engage the ends of the work as the cradle is tilted in either direction.

6. In a work holder,'the combination of a frame; a tilting cradle having end walls with cylinder receiving sockets open at the top; and a clamp operating sidewise against a cylinder arranged in the sockets.

7. In a work holder. the combination of a frame; a tilting cradle having end walls with cylinder receiving sockets open at the top; a clamp operating sidewise against a cylinder arranged in the sockets: and abutments adapted to engage a secured cylinder with the cradle tilted in either direction.

8. In a work holder, the combination of a frame having upwardly extending side posts; a cradle having side and end walls, the end walls having cylinder receiving sockets; a pin extending through the side posts and the cradle for pivotally mounting the cradle; a clamp for securing a cylinder in the sockets comprising a screw extending through the side wall of the cradle; and abutments on the frame adapted to engage the end of a secured cylinder with the cradle tilted in either direction.

In testimony whereof I have hereunto set my hand,

FEED M. BETTES.
